I am not sure if you are having the same problem I was, but I know my host had made some upgrades, and such w/ software, and servers, and I had an older version of CuteFTP and had to upgrade to CuteFTP 6.0 Pro to get in. Something to do with secure shell, or some shit.
But if that's not it, could be something in your settings. I know some hosts do not require SSL, or SSH. Some do. Varies by host and platforms I suppose. I have a two other hosts, and I could never log in w/ SSL like I have on my main stuff. They are just a basic FTP.
